The Atılım University Department of Mechanical Engineering started education in 2009, and offers graduate and doctorate degree programs, in addition to its undergraduate program. Our main goal is to graduate Mechanical Engineers who have the skills to design, analyze and synthesize; who are able to convert advanced technology and innovations into products; and who have the culture of research and cooperation. While our graduates reach this goal, they adopt the principle of life-long learning, and develop a sense of entrepreneurship, paying importance to professional ethics. With a curriculum prepared in line with the criteria of MÜDEK, we help our students develop themselves professionally, and socially. Graduates of mechanical engineering may be employed in many sectors and in a wide array of positions. Able to work under any field that involves production and energy conversion, graduates of the department may also gain expertise in fields such as aviation, automotive, or material engineering.

Abstract

In this research, recycled rubber-based composites are considered with glass bubble (GB) and fine gamma alumina fiber (γ-Al2O3) reinforcements. The effect of the reinforcements with matrix, fracture characteristics of the composite are studied by impact-loading tests (i.e., drop-weight tests). These test results are simulated by finite element analysis (FEM) and the results are compared with the experimental results. Microstructural and fracture surface analysis are carried out by means of scanning electron microscopy (SEM). Mechanical test results show that the reinforcement with glass bubbles and aluminum oxide ceramic fibers generally increase the damping capacity and fracture toughness of the composites. © 2023, The Society for Experimental Mechanics, Inc.
